GPS在矿山测量中的应用与研究

Application of GPS in mine survey

介绍了GPS技术在矿山测量应用中的优越性;建立矿区控制测量的方法,特别是应用于用传统方法已建立矿区测量控制网的矿山时,如何减少误差,利用已知点基线检测,求取相关修正参数,使其达到与原有矿区控制网的兼容;经过网络拓朴的选择与布设,矿区基准点及临时动态基站RTK的建立,达到了更经济方便的应用模式.

The merits of employing GPS in mine survey, and the method of establishing a controlled survey network in mine areas are described in the article. It focuses on reducing the survey error and determining a calibration factor of the new controlled survey network built by GPS survey with the original one built by the conventional method, by measurements based on the baselines of given points. The selection of a topological network and establishment of the benchmarks ＆ RTK are also discussed so as to gain a convenient and economic application of the GPS survey networks.
